BC needs 10mm of preload so after the springs are no more unfastened you'll want to jack the spring arm up and additonal 10mm (or .4") to set preload.
Dampers ! assuming the manufacturing unit diagram in this article - modify them within the reduce screw mount bolt area for lengthy vacation .... once you've ride top figured out with spring perches, decreased your car on the degree surface with all 4 tires on, unbolt reduce damper then screw down your body till 1/four-1/three of its known highest piston travel is previous the hubs bolt point. Then raise or compress the shock back again up to your bolt level that has a jack.
This can be an older thread, you may not receive a reaction, and could be reviving an aged thread. Remember to consider developing a new thread.
An xi with suspension mods could well be competing versus WRXs with LSDs in at least center and rear. Xi are open diff all around. There was a guy working a 330xi at nationals. He looked like he was driving pretty well, even so the subarus experienced a clear traction advantage.
also consider Vorshlag Varishock and Hyperco web sites - superior luck ! phone the tech folks for any fantastic tune - my K-Sports activities arrived with @#$% instruction and diagrams also ...could ditch the rear springs for a far better Hyperco setup afterwards and maintain the dampers
7. Very last problem may be very astounding. After i mounted rear, i lowered both equally springs to utmost (both equally collars screwed to base of that black threaded tube). But i forgot to measuer, how very low it had been = i dont really know what was default peak/distance amongst bottom Portion of threaded black tube and bottom ring.
i see one particular issue...when i jack car and unmount shock, arm will slide lil little bit down but i sense that there's lil bit of compression on spring. but its regular almost certainly.
Decrease the jack to enable the spring arm to hold. E46 coilovers Springs might be free at this time within their basket. To set preload and shocks, jack the spring arm back again up right up until the springs by themselves are no more free inside their mounting basket.
But How about rear spring ? I recognize, that rear spring dont have any preload since car is "sitting down" on spring and screwing collars up or down will only change car`s peak. Im correct?
They don't seem to be designed to support the load that a coilover rear imparts on them and that load path isn't accounted for by what you've there.
Include to estimate Only clearly show this consumer #seventeen · Jun 7, 2015 I am fascinated also in upgrading my suspension on my 325i and was thinking how one would price the solowers s1 when compared with BC be form coilovers, so far as driveability and trustworthiness.
Seems being precisely the same value for the e46 m3's in addition @ 744.00. Both equally my automobiles require suspension refresh, over likely will do the M3 to start with. I have been leaning towards koni/eibach, but noticed these @ a very good rate. Hoping to the suspension professionals to chime in. Many thanks!
Fantastic tune trip heights the two front and rear; then be sure to get wheels aligned and corner weight balanced by a Qualified understand how shop; and they're couple of and much involving in a few places.
I don't like the OEM BMW spring setup on any of such highly marketed buyer package variants readily available - its only for rear human body fall uses.
